It may be impossible to make a blanket statement about what type of fish is better. However, recent changes in the U.S. aquaculture industry has certainly increased the number of reasons to pick farm-raised over wild-caught.

These extensive regulations focus on reducing pollution, keeping the fish contained, improving the fish’s food, and eliminating contaminants. Due to these regulations, fish raised in U.S. farms actually may be better than wild-caught fish. Here’s why:

In 2004, one study found that farm-raised fish had increased levels of PCB, a chemical that could cause cancer. This study has been cited as a reason not to eat farm-raised fish, but its methodology has been criticized by many scientists. More recent research shows that health benefits outweigh the possibility of contamination.

Another large concern with farm-raised fish is the use of pesticides and antibiotics. However, these have been outlawed in U.S. farms. Also, fish that are typically farm-raised, such as catfish, tilapia, and salmon, tend to be lower in mercury. On the other hand, high-mercury fish, such as swordfish, king mackerel, tilefish, shark, and tuna are usually wild-caught.

When compared to wild-caught fish, which can be naturally exposed to toxins, U.S. farm-raised fish are about equally as likely to be contaminant-free. As long as you check to make sure it was raised in the U.S., you can be confident of your fish’s cleanliness.

As reported by WTOP, Mary Ellen Camire, professor of food science and human nutrition at the University of Maine, explains, “You have to send the fishing boats out into the ocean, they catch the fish and then have to come back, then take their truck to market, so [wild-caught fish] are not very carbon-footprint friendly.” On the other hand, fish farms can be built closer to or even within cities decreasing the amount of transportation.

In the past, fish farms ground up tiny fish to make their feed, which was not a very sustainable practice. However, farms have begun to produce their own worms and algae to feed the fish, making them more environmentally-friendly.

Because of low demand, farm-raised fish, especially salmon, tends to cost significantly less than wild-caught. But as the nutritional and environmental gap between the two types of fish closes, it may no longer be worth it to splurge for wild-caught fish.
